Solution Overview

Problem

Conventional compression bandages fail to adequately account for the varying geometries and required compression forces across different areas of the body, leading to inconsistent application and compression effects.

Innovation Solution

The bandage features varying thread densities in the warp and/or weft thread systems along its length, allowing for customized compression properties and improved application behavior by adjusting thread density and width to match specific body regions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional compression bandages with uniform thread density are used, then the bandage structure is simple and easy to manufacture, but the compression effect is inconsistent across different body areas with varying geometries

Engineering Contradiction:
Improvecompression effect consistencyVSAvoidthread density variation
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The bandage is designed with spatially varying thread densities, where different sections have different warp and/or weft thread densities to match the specific geometric requirements of different body areas. This allows the compression bandage to provide appropriate compression force for each local region, improving compression effect consistency across varying geometries.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The invention changes the structural parameters of the bandage by varying the thread density (number of warp and/or weft threads per unit length) along the longitudinal direction. This parameter variation enables the bandage to adapt to different body geometries and provide consistent compression效果 across different areas.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If bandages of different widths are used to accommodate different body geometries, then the compression effect can be adjusted for different areas, but the device complexity and application process become more complex

Engineering Contradiction:
Improvecompression force adjustmentVSAvoidmultiple bandage configurations
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

Instead of using multiple bandages of different widths, the invention implements local quality variation within a single bandage by adjusting thread density in different longitudinal sections. This allows compression force adjustment for different body areas while maintaining a single, unified bandage structure.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The single bandage design with variable thread density serves multiple functions: it can accommodate different body geometries, provide adjustable compression forces, and simplify the application process, replacing what would otherwise require multiple specialized bandages.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If the bandage width is varied to match body geometries, then application behavior improves for different areas, but the manufacturing precision and thread density control become more difficult

Engineering Contradiction:
Improveapplication behaviorVSAvoidthread density variation control
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The invention achieves improved application behavior by implementing local quality variation through controlled thread density changes in different sections of the bandage, allowing the material to adapt to different body geometries while maintaining manufacturability.

Inventive Principle:
Principle #3Local quality

AI summary

The invention relates to a compression bandage for placing on the human or animal body, comprising a planar sheet material (11) with a longitudinal direction (L) and a transverse direction (Q), and two transverse edges (11a, 11b) lying opposite each other in the longitudinal direction (L), and two longitudinal edges lying opposite each other in the transverse direction (Q), wherein the sheet material (11) is made of a fabric with a warp (20) and a weft (30) system of threads, wherein at least one of the thread systems (20, 30) comprises elastic threads, wherein the thread density in the warp and/or weft system of threads (20, 30) is varied in the longitudinal direction (L) of the bandage (10), such that at least one portion (A, B, C) of the bandage (10) in the longitudinal direction (L) has a warp and/or weft thread density different than an adjacent portion.
